Abstract: A multifunction stabilizer for attachment to a ladder includes: a frame including a base, a first arm connected to a first lateral side of the base and extending in a forward direction, a second arm connected to a second lateral side of the base opposite the first lateral side and extending in the forward direction, and a bracket-engagement member connected to the base and extending in a rearward direction opposite the forward direction; a rearward bracket including a base-engagement member, a first ladder-engagement wing extending from a first lateral end of the base-engagement member, and a second ladder-engagement wing extending from a second lateral end of the base-engagement member opposite the first lateral end; and a fastener for selectively locking the bracket-engagement member into engagement with the base-engagement member such that capture channels for receiving the rails of a ladder are defined between the arms and the ladder-engagement wings.
